ATTACHMENT FOR METAL-PLAN ERS.

Y SPECIFICATION forming part of Letters Patent No. 446,074, dated February 10, 1891.

Application filed J une 21, 1890. Serial No. 358.362. (No model.)

- planing, shaping, and slo-tting metal, and has for its object the construction of an attachment for holding cutting-tools, and is constructed to be secured to the movable or reciprocating bed of the class of machinery specified.

The invention will be hereinafterdescribed,

vand particularly pointed outin the claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a perspective ot' my invention; Fig. 2,*a plan; Fig. 3, an end view of one side or one-half of the device shown in Figs. l and 2; Fig. 4, an enlarged perspective of a piece of metal after having been planed or shaped; Fig. 5, an enlarged end view of a T-shaped piece of metal; Fig. 6, a perspective of a modification in the form of the attachment; Fig. 7, an end view on a reduced scale; Fig. 8, a perspective of a piece of metal with a T-shaped groove in it, and Fig. 9 a similar view of a piece of meta-l with a rectangular slot in one of its edges.

Reference being had to the drawings and the letters thereon, A indicates a cast-metal frame, which is provided with bolt-holes d for securing it to the reciprocating bed of a planing, shaping, or slotting` machine. On each side of the frame is a series of recesses l), to receive cutters c, which `are graduated so that each cutter from the entering end of the frame projects a little farther than the cutter pr'eceding it, so that the work will be distributed over the entire length of the frame A and its cutters c. The cutters are securely held in their respective recesses by a clamping-plate B over each series, which is attached to the frame A by bolts d, passing through the plates and engaging with the frame, and the cutters are adjusted to any proper vertical alignment by'screw-bolts c, passing through and engaging with the plates B and bearing upon the cutters, and by the screw-bolts f, projecting through the lateral extensionsV C D ot the frame and from the lower side thereot'. Their horizontal alignment and adjustment are effected by screw-bolts g,bear-ingupon the outer end of the cutters.

In the extensions C D are formed longitudinal grooves h i and slots k, which are equal in width to the width of the cutters and form passages for the withdrawal of the cutters for the purpose of sharpening or1 renewal. The lugs Z on the outer edges of the extensions C D are provided with projections y m, under which the screw-threaded blocks nare held against vertical displacement. The screwbolts g pass through and engage with the threaded apertures 0 in the blocksnand bear upon the critters, as shown in Figs. l and 2.

In the center ot' the frame is a dovetailed n groove p, in which is inserted a guide q for centering and steadying the article to be wrought upon. This guide may be of Various configurations and interchangeable to suit various kinds of articles. The guide shown is designed for use in planing an article such as E, (shown in Fig. 4,) in which there is a square or right-angled central opening r on the under side, which engages with the guide while the right-angled portions s t are being planed. For some forms the guide q is removed and a projection on the article run in the groove p. n Y

F in Fig. 5 indicates a T-shaped piece of metal,in which the right-angled portions w 'v have been planed.

In the use of my attachment the article to be planed is secured to the usual cross-piece of the planer to which the cutting-tool is lordinarily attached and in line with the cutters in the -attachment or frame secured to the planer-bed, and the entire work of planing done during one movement of the planer-loed by the cutting ot the graduated cutters.

In Figs. 6 and 7 is shown a modification, in which the cutters are of a form to cut or finish a T-shaped slot w such as shown in the piece G in Fig. 8 when both sides of the cutters are used, or a rectangular slot cc such as shown in piece Il in Fig. 9 when only one IOO 5 The width ot the slot cut may side of the cutters is used. The cutters care adjusted horizontally by screw-bolts g and vertically by bolt f, bearing upon the under side of a pair of cutters. Y

be increased by placing a liner between the cutter in a manner well known to the skillful mechanic, and cutters of various shapes may be employed within the scope and spirit of my invention.

Having thus fully described my invention, what I claim isl. An attachment for metal-planers, consisting of a east-metal frame constructed 'to he detachably secured to a planer-bed and provided with a series of recesses, and graduated cutters in said recesses, in combination with devices for adjusting the cutters vertically and horizontally, and a guide for engaging the article wrought upon, substantially as described.

2. An attachment for metal-planers, consisting of a east-metal frame provided With lateral extensions having recesses, longitudinal grooves and slots, graduated. cutters in said recesses, and a detachable covering-plate, in combination with screw-threaded blocks in said grooves and screws for adjusting the cutters, substantially as described.

3. An attachment for metalplaners,con sisting of a cast-metal trame constructed to be detachably secured to a planer-bed and provided with series cit" recesses on opposite sides ot the frame, amd graduated cutters in said recesses, in combination with screws for adjusting the cut-ters vertically and horizontally, and a guide b fetween the opposite cutters for engaging the article wrought upon, substantially as described.

4. An attachment for 1netal-planers,con sisting of a cast-metal frame provided with series of recesses on opposite sides of the frame, graduated cutters in said recesses,`a detachableV covering-plate, and a longitudinal guide between the series of cutters, in combination with screws for adjusting the cutters, substantially as described.

5. An attachment for metal-planters, con- 'sisting of a cast-metal frame provided with series of oppositely-arranged recesses, graduated cutters in said recesses, and an interchangeable longitudinal guide between the cutters, in combination with horizontal screws and blocks in grooves in the extensions of the frame for adjusting the cutters horizontally, and screws for adjusting them vertically, substantially as described.

In testimony whereof I a'ix my signature in presence ot two witnesses.
